All materials used
in our turbine assembly were made from stainless steel, aluminum, plastic and
wood. These materials were selected
specifically to minimize weight and size, to maximize voltage output. The shaft was secured using plastic ball
bearings with glass balls (non-magnetic objects), which showed the biggest
improvement in the design of the wind turbine because the shaft speed
increasing tremendously and the stability stiffening. We also wired the coils in a series to
increase voltage output, and used speaker terminals to connect each coil with
one another, for ease of replacement.
The
whole assembly was manufactured so that each component could be replaced
without major disassembly of the whole turbine. The housing was screwed in place so that
the top half could be lifted or removed to do any electrical or mechanical work
to the interior of the turbine. One
improvement we would have liked to add was a braking system, because of the
high rpm the turbine shaft was spinning.
- Measure the generator resistance with
the digital Voltmeter (DVM)
- Place a small piece of reflective tape
to a dark surface of the turbine.
- Connect the DVM to the turbine output
leads.
- Connect one side of the resistor load
to the DVM common (black).
- Start the fan and adjust the speed and
position for the minimum turbine output (must have AC signal).
- Record the minimum and maximum wind
speed.
- Record the average RPM, DVM voltage
and DVM frequency for each load condition.
- In crease the wind speed for the next
target speed that is obtained.
- Repeat the procedure until the maximum
wind speed is obtained.
- Turn in the Team data sheet to the
instructor for grading.
Turbine
Open Circuit Voltage Test Results
As a group we
worked together to construct one of the best turbines. Producing a maximum of
30 volts, smashing the previous record by more than half. This turbine was
designed to be high performing and easily operated on. Which makes it a breeze
to fix any potential problems or for future modifications and improvements.
During the course of this project we learned that you have to always test the
little things first. When we were trying to find out why one of our original
turbines wasnÕt working we over looked the fact that the magnets might have
been placed on the wrong sides, thus causing no light because all the polls
were facing the same direction. After that we made sure we never over looked
anything during the fabrication of the new turbine. We also learned how much
attaching a load acted as a breaking mechanism to slow the propeller down. In
conclusion, we pulled together as a team and raised the bar much higher by
created one of the best turbines CCRI has ever seen.
